Application December 17, 1945, Serial No. 635,507

The invention as described herein, and illustrated in the accompanyingdrawings, consists of a container for drills, an object of which is toprovide a case for holding a set of drills graduated in diameter andlength so arranged that a drill of a desired size may be instantlylocated.

Another object of the invention is to provide a drill case arranged tohold a series of drills of graduated lengths in vertical position andfrom which the drills can not be displaced therefrom through invertingthe case.

A further object of this invention is to provide a molded drill standprovided with a transparent plastic cover so arranged to retain eachdrill in its apportioned position in the stand.

A still further object of the invention is the provision of meanswhereby delicate drills ranging from the smallest diameter up can beorderly arranged and supported vertically in order that a desired drillmay be instantly located.

Another object of the invention is to provide a drill stand having acover provided with means for retaining each drill in its apportionedposition and means whereby the cover must be placed in a predeterminedposition upon the stand.

Other features and advantages will become more readily apparent from thefollowing description and the accompanying illustrative drawings inwhich:

Figure l is an elevational view of the case,

Figure 2 is a sectional View on line 2-2 thereof,

Figure 3 is a sectional View on line 3-3 of Figure l,

Figure 4 is a sectional view on the same line looking toward arrow 4,

Figure 5 is a detail of a clamping ring, and

Figure 6 is a bottom plan view of a base member.

While one embodiment of the invention is illustrated in the abovereferred to drawings, it is to be understood that they are merely forthe purpose of illustration and that various changes in construction maybe resorted to in the course of manufacture in order that the inventionmay be utilized to the best advantage according to circumstances whichmay arise, without in any way departing from the spirit and intention ofthe device, which is to be limited only in accordance with the appendedclaims. And while there is stated the primary field of utility of theinvention it remains obvious that it may be employed in any othercapacity wherein it may be found applicable.

In the accompanying drawings, and in the following specification, thesame reference charaoters are used to designate the same parts andelements throughout' and in which I0, refers to the invention in itsentirety and II, indicates a base and I2, a cover therefor. The base isof molded material either plastic or metal and is of inverted cup shape,the vertical flange I3, of whichl terminates at its lower end in anoutwardly extending annular flange I4, upon which is adapted to` seatthe lower end I5, of said cover I2. v

Thek top wall I6, of the base is provided with a series of annulararranged depending cylinders Il, I8, etc., in graduated lengths andwhichare also integral with the side wall I9, of the base. From the uppersurface 20, of the said base are blind bores or holders 2I, 22, etc.,formed in the molding process and which are graduated in diameter anddepth to receive standard drills 23 and 24, of graduated sizes, the saidholes being of diameters and depth to receive only the Shanks 25 and 26,of the drills intended to seat therein. Each of the said holes isprovided with an indicia 2l, to indicate the size of its particulardrill, these indices are sunk into the said surface 28, in the castingprocess. There is also provided a second annular series of wells orholes 28, 29, etc., inwardly of the outer series which provide supportsfor other sizes of drills (not shown) as indicated by the indicia 30.

lThe cover I2, is moulded preferably from Lucite or some other plasticmaterial and its upper wall 3|, has projecting from the inner peripheralsurface 32, thereof a depending spiral ange 33, integral with the saidtop wall and the side wall 34, and which is inclined longitudinally fromits deepest terminal 35 to flush with said surface 32, whereby theflange will seat against the upper ends of each of the drills 23 and 24,and hold the same from accidentally leaving their seats in the base,when the cover is seated thereon.

The side wall 34, of the cover at its lower end IS, terminates in anannular outwardly extending flange 38, which seats upon the base angeI4. Projecting up from the flange I4, is a vertical guide rib or key 39,which is adapted to align with the positioning slot or notch 40 in theflange 33, of said cover I2, when seated on the base and which isadapted to extend into the keyway 4I, formed in the lower edge of thecover, whereby the cover can be placed upon the base in one positiononly so that the ange 33, will conform to the stepped relation of theterminals 46, of said drills. Encornpassing the lower end of the coverand seating upon the flange 38 thereof, is a resilient open ring 4l, theends 48 Changes in shape, size and rearrangement details and parts suchas come within the puri view' of the invention claimed may be resortedto, in actual practice, if desired.

and 49, of which form a gap 50, through which the said key 39 projects.This ring will tend to bind the lower end of the cover frictionally uponthe base and also forms a ringer grip by means of which the cover may beremoved from the base.

From the foregoing specification it will become apparent that theinvention disclosed will adequately accomplish the functions for whichit has been designed and in an economical manner and that its`simplicity, accuracy and ease ofoperation are such as to provide a,relatively inexpensive device considering what it will accomplish yvertical key, said cylinders being formed with verand that it will nd animportant place in the art to which it appertains when once placed onthe market.

It is thought that persons skilled 'in the art to which the inventionrelates will be able to obtain a clear understanding of the inventionafter considering the description` in connection with the drawings.Therefore, a more lengthy description is regarded as unnecessary.

vof

i Having now described the invention that which is claimed to be new anddesired to be procured by Letters Patent is:

A drill case comprising a raised cylindrical base formed with aplurality of circumferentially vdisposed depending cylinders ofprogressively lengthening height and an annular flange formed about itslower end being formed with an upstanding tical drill receiving boresfor drills of various lengths and diameters to be disposed inprogressive sequence in said bores, a cylindrical cover formed with anannular ange about its lower endfhaving a positioning notch formedtherein receiving said key when said cover is positioned upon said base,a spiral positioning flange Xed on the inner top surface of said coverfor engaging the upper ends of the various length drills disposed insaid bores to secure the drills immobile in said case, and a splitlocking ring disposed about the notched lower end of said coverresiliently securing said cover in closed position upon said base.
